Research Facts
Dr Ralph and Mrs Olga Crawford donated their extensive Canadian dental collection to the DCF to create the museum in 1997; further donations were received while Dr Crawford was Curator Emeritus at the Dental Canada Museum until its closure in 2008; this item was donated by Dr. Christopher Clark from Vancouver, British Columbia; Frank Ritter had settled in Rochester, NY as a cabinet-maker before manufacturing the Stuck dental chair in 1888, the first chair with a round metal base; later models featured the first use of hydraulics to raise and lower the chair, a revolution for its time; the design was not significantly changed until the 1960s
